While CG PUSCH2 is not in a Fixed Frame Period (FFP) of the base station, it needs to transmit in a terminal-initiated Channel occupied Time (UE-initiated COT), but the terminal does not initiate a Channel Occupied Time (COT) at CG PUSCH1, resulting in that CG PUSCH2 cannot transmit.

Detailed Description

The technical solutions in the embodiments of the present application will be described below clearly with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of protection of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in other sequences than those illustrated or otherwise described herein, and that the terms "first" and "second" used herein generally refer to a class and do not limit the number of objects, for example, a first object can be one or more. In the specification and the claims, "and" indicates at least one of the connected objects, and the character "/" generally indicates that the former and latter related objects are in an "or" relationship.

It is noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE)/LTE Evolution (LTE-Advanced) systems, but may also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal Frequency Division Multiple Access (OFDMA), single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" are often used interchangeably in embodiments of the present application, and the described techniques may be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, but the techniques may also be applied to applications other than NR system applications, such as 6 th generation (6 th generation) ^th Generation, 6G) communication system。

In order to facilitate understanding of the embodiments of the present application, the following technical points are introduced below:

in future communication systems, a shared spectrum such as an unlicensed band (unlicensed band) may be used as a supplement to a licensed band (licensed band) to help an operator expand services. In order to maintain consistency with NR deployment and maximize NR-based unlicensed access as much as possible, unlicensed frequency bands may operate in the 5GHz,37ghz and 60GHz frequency bands. Since the unlicensed frequency band is shared by multiple technologies (RATs), such as Wireless Fidelity (WiFi), radar, long Term Evolution (LTE) -Licensed-Assisted Access (LAA), etc., in some countries or regions, the unlicensed frequency band must meet regulations (regulations) to ensure that all devices can fairly use the resources, such as Listen Before Talk (LBT), maximum Channel Occupancy Time (MCOT), etc. When the transmission node needs to send information, it needs to do LBT first, and then power detection (ED) is performed on the surrounding nodes, and when the detected power is lower than a threshold, it considers that the channel is idle (idle), and the transmission node can send. Otherwise, the channel is considered to be busy, and the transmitting node cannot transmit. The transmission node may be a base station, a terminal (such as a User Equipment (UE)), a Wireless Fidelity (WiFi) Wireless Access Point (Access Point, AP), or the like. After the transmission node starts transmission, the Channel Occupancy Time (COT) cannot exceed the MCOT.

Frame Based Equipment (FBE) network operation:

FBE means that the transmission/reception timing of the device adopts a periodic structure, and the period is FFP.

The FBE node adopts a channel access mechanism based on LBT to occupy the channel. A node that initiates a transmission sequence including one or more consecutive transmissions is referred to as an Initiating node (Initiating Device), and other nodes are referred to as Responding nodes (Responding devices). The FBE node may be an initiating node, a responding node, or both.

An example of the operation of the initiating node is shown in figure 2. The operating requirements include:

(1) A Fixed Frame Period value set supported by the nodes is stated by a device manufacturer, and each value is required to be within the range of 1-10 milliseconds (ms). The transmission can only be started at the start of a Fixed Frame Period. A node may change its currently applied Fixed Frame Period, but its frequency cannot be higher than 200ms once.

(2) Before starting transmission at the starting time of a Fixed Frame Period, the initiating node will perform Clear Channel Assessment (CCA), and if it is determined to be idle, it may immediately transmit, otherwise, it is not allowed to transmit within the duration of the next Fixed Frame Period (except Short Control signaling Transmissions specified by regulatory requirements). That is, the originating node needs to perform one-shot (LBT) before transmission.

(3) In a Fixed Frame Period which has started to be sent, the total time length which can be transmitted by the corresponding initiating node without re-estimating the availability of the channel is defined as COT. The initiating node may transmit multiple times on the designated channel within the COT without performing an additional CCA, as long as the time interval between adjacent ones of these transmissions does not exceed 16 microseconds (μ s). If the time interval between adjacent transmissions within the COT exceeds 16 mus, the initiating node needs to perform an additional CCA before continuing to transmit, and continues to transmit only when the CCA determines that the channel is clear. The time interval between all adjacent transmissions takes into account the COT duration.

(4) The originating node may grant usage rights for a given channel for certain periods of time within the COT to 1 or more associated responding nodes for transmission.

(5) The COT cannot be longer than 95% of the Fixed Frame Period, and an Idle Period (Idle Period) follows the COT and continues until the start time of the next Fixed Frame Period ends, so that the length of the Idle Period is at least 5% of the Fixed Frame Period, and the minimum value is 100 μ s.

(6) After a node correctly receives a data packet for it, it may transmit a management and control frame (e.g., an Acknowledgement (ACK) frame) corresponding to the data packet on a designated channel directly and immediately without CCA. The node needs to ensure that these continuously transmitted frames cannot exceed the above-mentioned maximum COT duration.

After receiving the authorization of the initiating node to use the designated channel for a certain period of time, the responding node performs the following operations:

the responding node does not need to perform CCA prior to transmission if it initiates a transmission at most 16 mus after the initiating node indicates the end of the last transmission of the grant; otherwise, executing CCA before the start of the authorized transmission time interval, if the channel is judged to be busy, discarding the authorization, otherwise, starting transmission on the appointed channel, occupying the rest part of COT in the current Fixed Frame Period at most, starting multiple transmissions in the time range of the rest part, and discarding the authorization after the transmission is finished as long as the time interval of adjacent transmissions does not exceed 16 mus.

(II) FBE in Release 16 (Rel-16):

in the Rel-16 Unlicensed band new air interface (NR-U), only the base station (next Generation Node B, gNB) may initiate the COT, and if the UE performs uplink transmission, the UE needs to share the COT of the gNB. That is, the UE needs to detect whether the gNB initiates the COT before uplink transmission, and if so, uplink transmission is performed in the COT of the gNB, and the transmission duration cannot exceed the length of the COT of the gNB. The UE may determine that the gNB initiates the COT by detecting any downlink signal. Here, the COT of the gNB is a COT initiated by the gNB, i.e., a gNB-initiated COT.

(III) FBE in version 17 (Rel-17):

in Rel-17 high-reliability and Low-Latency Communications (URLLC), the gNB and the UE may use different FFP periods and/or different FFP start positions, respectively. If the UE wants to perform uplink transmission, LBT may be performed in an idle period (idle period) of its FFP, and if it is detected that the channel is empty, it initiates COT to perform uplink transmission. Meanwhile, the COT of the UE may also be shared to the base station, and the base station may send a downlink signal, such as a control signal, a broadcast signal, data, and the like, to the UE initiating the COT or other UEs within the shared COT. Here, the COT of the UE is a UE-initiated COT, i.e., a UE-initiated COT.

In Rel-17, since the UE can either initiate COT or share the gNB-initiated COT, the UE needs to agree with the gNB on the channel access mechanism for CG UL transmission. There are two selection mechanisms in the existing discussion:

in semi-static channel access mode, when a UE may operate as a UE-initiated COT, one of the following alternatives is selected to determine whether a configuration granted uplink transmission aligned with a UE FFP boundary (boundary) and ending before an idle period of the UE FFP is based on a UE-initiated COT or a shared gNB-initiated COT:

alternative a: if transmission is restricted to within the gNB FFP before the idle period of the gNB FFP, and the UE has determined that the gNB initiated the COT, the UE assumes that the configuration grant uplink transmission corresponds to the gNB initiated COT. Otherwise, the UE assumes that the configured authorized uplink transmission corresponds to a UE-initiated COT

Alternative b: the UE assumes that the configuration grant uplink transmission corresponds to a UE-initiated COT.

When CG uplink transmission (UL transmission) and UE FFP boundaries are aligned, for alternative a, when CG uplink transmission is limited within FFP of gNB and ends before idle period of gNB, then UE shares gNB-initiated COT. In other cases, the UE employs UE-initiated COT for CG uplink transmission. For alternative b, the UE assumes that CG uplink transmission should use UE-initiated COT transmission. For alternative a, since the CG uplink transmission is limited to the FFP of the gNB, it is not clarified whether the CG uplink transmission is the first available CG uplink transmission burst (burst) or all possible CG uplink transmission bursts. The problem in fig. 1 arises if it is the first CG UL uplink transmission burst that can be used.

Referring to fig. 3, a block diagram of a wireless communication system to which embodiments of the present application are applicable is shown. The wireless communication system includes a terminal 31 and a network side device 32. Wherein, the terminal 31 may also be called as a terminal Device or a User Equipment (UE), the terminal 31 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: smart watches, bracelets, earphones, glasses, and the like. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 31.

The network-side device 32 may be a Base station or a core network, where the Base station may be referred to as a node B, an enodeb, an access Point, a Base Transceiver Station (BTS), a radio Base station, a radio transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home enodeb, a WLAN access Point, a WiFi node, a Transmit Receive Point (TRP), a radio access network node, or some other suitable term in the field, as long as the same technical effect is achieved, the Base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present application, the Base station in the NR system is only used as an example, but the specific type of the Base station is not limited.

Referring to fig. 4 and 5, an embodiment of the present application provides a transmission method, where an execution main body of the method may be a terminal, and the method includes: step 401 and step 402.

Step 401: the terminal determines whether to perform uplink transmission (UL transmission) in a first channel occupying time or in a second channel occupying time;

step 402: the terminal sends indication information to network side equipment, wherein the indication information indicates whether the terminal carries out uplink transmission in the first channel occupation time or not, or the indication information indicates whether the terminal carries out uplink transmission in the second channel occupation time or not;

the first channel occupation time is a channel occupation time initiated by the terminal, the first channel occupation time may be represented by a UE-initiated COT (UE-initiated COT), the second channel occupation time is a channel occupation time initiated by a network side device, and the second channel occupation time may also be represented by a base station-initiated COT (gNB-initiated COT).

In an embodiment of the present application, the step of determining, by the terminal, whether to perform uplink transmission in the first channel occupied time includes:

under the condition that the uplink transmission is aligned with the fixed frame period boundary of the terminal and the terminal is configured with first information, the terminal determines whether to perform uplink transmission within the first channel occupation time;

wherein the first information comprises: and the terminal autonomously selects the related information of the first channel occupation time, such as at least one of a configured grant retransmission timer (CG-retransmission timer-r 16) of release 16 or a configured grant uplink control information (CG-UCI).

Illustratively, in the case of UL transmission and UE FFP boundary alignment, the UE is configured with relevant parameters/modes for UE to autonomously select the initiated COT, such as: in the case of at least one of CG-retransmission timer-r16 or CG-UCI, the UE may decide on its own whether to perform UL transmission in the UE-initiated COT.

In an embodiment of the present application, the step of determining, by the terminal, whether to perform uplink transmission in the first channel occupation time includes:

the terminal determines to perform uplink transmission within the first channel occupation time under the condition that uplink transmission is aligned with the terminal fixed frame period boundary and the terminal is not configured with the first information;

wherein the first information comprises: and the terminal autonomously selects the relevant information of the first channel occupation time.

Illustratively, in the case of UL transmission and UE FFP boundary alignment, the UE does not configure the relevant parameters/modes for UE to autonomously select the initialized COT, such as: in the case of at least one of CG-retransmission timer-r16 or CG-UCI, the UE may perform UL transmission in the UE-initiated COT.

the terminal determines to perform uplink transmission within the second channel occupation time under the condition that uplink transmission is aligned with the boundary of the terminal fixed frame period and the terminal is not configured with first information and the uplink transmission is within the network side device fixed frame period and ends before an idle period (idle period) of the network side device fixed frame period;

Illustratively, in the case of UL transmission and UE FFP boundary alignment, the UE does not configure the relevant parameters/modes for UE to autonomously select the initiated COT, such as: in the case of at least one of CG-retransmission timer-r16 or CG-UCI, the UE performs UL transmission in the shared gbb-initiated COT if the UL transmission is within the network side device FFP and ends before the idle period of the gbb FFP.

In one embodiment of the present application, the indication information includes one or more of:

(1) A first field in the uplink control information, the first field indicating the network side device to share the relevant information of the first channel occupation time;

for example, if the first domain indicates that the network-side device shares the first channel occupation time, it indicates that the terminal performs uplink transmission in the first channel occupation time, and if the first domain indicates that the network-side device does not share the first channel occupation time, it indicates that the terminal does not perform uplink transmission in the first channel occupation time.

The first field may also be represented by a COT sharing information field (COT sharing information field). Exemplarily, adding a configuration combination (configured combination) in the configured grant channel occupancy time sharing list (cg-COT-SharingList) indicates that the terminal does not perform UL transmission in the UE-initiated COT. When the COT sharing information indicates the configuration combination, it indicates that the terminal does not perform UL transmission in the UE-initiated COT.

(2) A second field in the uplink control information, where the second field indicates whether the terminal performs uplink transmission in the time occupied by the first channel or indicates whether the terminal performs uplink transmission in the time occupied by the second channel;

for example, the second domain includes 1-bit indication information, a value of "1" indicates that the terminal performs uplink transmission in the time occupied by the first channel, a value of "0" indicates that the terminal does not perform uplink transmission in the time occupied by the first channel or that the terminal performs uplink transmission in the time occupied by the second channel, or a value of "1" indicates that the terminal performs uplink transmission in the time occupied by the second channel, and a value of "0" indicates that the terminal does not perform uplink transmission in the time occupied by the second channel or that the terminal performs uplink transmission in the time occupied by the first channel.

(3) A reference signal sequence (RS sequence) indicating whether the terminal performs uplink transmission in the first channel occupying time or indicating whether the terminal performs uplink transmission in the second channel occupying time;

exemplarily, reference signal sequence 1 indicates that the terminal performs uplink transmission in the first channel occupation time, and reference signal sequence2 indicates that the terminal performs uplink transmission in the second channel occupation time.

For example, the Reference Signal sequence may be a Demodulation Reference Signal (DMRS), an uplink Sounding Reference Signal (SRS), or the like.

(4) A preamble used for random access, where the preamble indicates whether the terminal performs uplink transmission in the first channel occupation time or indicates whether the terminal performs uplink transmission in the second channel occupation time;

illustratively, preamble 1 indicates that the terminal performs uplink transmission in the first channel occupying time, and preamble 2 indicates that the terminal performs uplink transmission in the second channel occupying time.

(5) Dedicated uplink signaling.

Illustratively, the terminal indicates to the network side device through dedicated uplink signaling whether to perform UL transmission in the UE-initiated COT. The dedicated uplink signaling may be a 1-bit dedicated signaling (dedicated signaling) carried on the PUCCH, where a value of "1" indicates that the terminal performs uplink transmission in the first channel occupied time, a value of "0" indicates that the terminal does not perform uplink transmission in the first channel occupied time or that the terminal performs uplink transmission in the second channel occupied time, or a value of "1" indicates that the terminal performs uplink transmission in the second channel occupied time, and a value of "0" indicates that the terminal does not perform uplink transmission in the second channel occupied time or that the terminal performs uplink transmission in the first channel occupied time.

(1) Configuring authorized uplink transmission;

(2) Dynamic Grant (DG) uplink transmission;

(3) Authorizing a configuration (per configured grant) for each configuration;

(4) Respectively, a configuration grant, a dynamic grant, an SRS, a Physical Uplink Control Channel (PUCCH), or a PRACH configuration.

Embodiments of the present application will be described below with reference to example one to example four.

Example one

When the UL transmission and the UE FFP boundary are aligned, if the UE configures at least one of CG-retransmission timer-r16 or CG-UCI, the UE may select whether to perform the UL transmission in the UE-initiated COT or in the gNB-initiated COT according to the UL transmission.

(1) If the current UL transmission limit (context) is within the FFP of the base station (next generation node B, gNB) and no new UL transmission is subsequently expected to exceed the end time of the gNB FFP, the UE performs UL transmission in the gNB-initiated COT.

Wherein the new UL transmission is not consecutive to the current UL transmission and arrives after the current UL transmission.

(2) If the current UL transmission context is within the FFP of the gNB and a new UL transmission is subsequently expected to exceed the end time of the gNB FFP, the UE performs the UL transmission in the UE-initiated COT.

Wherein the new UL transmission is not contiguous with the current UL transmission and arrives after the current UL transmission.

(3) The UE always chooses to perform UL transmission in the UE-initiated COT.

(4) The UE always chooses to perform UL transmission in the gNB-initiated COT.

Example two:

the UE may indicate to the gNB whether to perform UL transmission in the UE-initiated COT through uplink signaling.

(1) When CG-UCI is configured, the UE indicates to the gNB through the CG-UCI whether to perform UL transmission in the UE-initiated COT.

a. Indicated to gNB by COT sharing information filtered in CG-UCI.

i. When the COT sharing information filtered indicates that the gNB may share a COT (share COT), for example, information such as a start position and a length of downlink transmission performed by the gNB is indicated, it indicates that the UE performs UL transmission in the UE-initiated COT.

When COT sharing information filtered indicates that gNB does not share (no sharing), it indicates that UE does not perform UL transmission in UE-initiated COT.

Adding a configuration combination (configured combination) to the "cg-COT-sharingList" indicates that the UE has not transmitted UL transmission in the UE-initiated COT. When the COT sharing information indicates the configuration combination, it indicates that the UE does not perform UL transmission in the UE-initiated COT.

b. Indicating to the gNB whether the UL transmission is performed in the UE-initiated COT through a proprietary field in the CG-UCI.

i. The proprietary field may be represented by 1 bit, and a value of 1 or 0 may indicate that the UE has or does not perform UL transmission in the UE-initiated COT.

(2) The UE indicates whether to perform UL transmission in the UE-initiated COT through RS sequence (such as DMRS, SRS), which includes the following two ways:

a. selecting a specific RS sequence, wherein RS sequence 1: indicating that the UE shares the gNB-initialized COT; RS Sequence2, indicating that the UE adopts UE-initiated COT.

b. Dividing the RS sequences into at least two groups, wherein any RS sequence belonging to group 1 represents that the UE shares the gNB-initialized COT, and any RS sequence belonging to group 2 represents that the UE adopts the UE-initialized COT.

(3) The UE indicates whether to perform UL transmission in the UE-initiated COT through a Preamble (for PRACH), including the following two ways:

a. selecting a specific Preamble, wherein the ratio of Preamble 1: indicating that the UE shares the gNB-initiated COT; preamble 2, indicating UE adopting UE-initiated COT

b. The method comprises the steps of dividing preambles into at least two groups, wherein any Preamble belonging to group 1 represents that UE shares gNB-initialized COT, and any Preamble belonging to group 2 represents that UE adopts UE-initialized COT

(4) The UE indicates to the gNB through dedicated uplink signaling whether to perform UL transmission in the UE-initiated COT. A 1-bit truncated signaling may be carried in the PUCCH.

It should be noted that: indicating whether the UE performs UL transmission in the UE-initiated COT is equivalent to indicating whether the UE initiated the COT, and is also equivalent to indicating whether the UE shares the COT of the gNB. That is, the UE performing UL transmission in the UE-initiated COT is equivalent to the UE initiating the COT by itself, and is equivalent to the UE not sharing the gNB-initiated COT. Conversely, the UE does not perform UL transmission in the UE-initiated COT is equivalent to the UE not having its own initiated COT, and is equivalent to the UE sharing the gNB-initiated COT.

Example three:

when the UL transmission and the UE FFP boundary are aligned and the UE is not configured with at least one of CG-retransmission timer-r16 or CG-UCI, the UE transmits the UL transmission in the UE-initiated COT. That is, as long as any one of the two parameters does not exist, the UE initiates the COT by itself for uplink transmission. At this time, the UE does not need to indicate whether share COT is available to the gNB, and the gNB determines whether the UE itself initiates COT according to whether at least one of retransmission timer-r16 and CG-UCI is configured at the same time. If the UE initiates the COT, the default gNB may be able to share the UE-initiated COT.

Example four:

when the UL transmission and the UE FFP boundary are aligned and the UE is not configured with at least one of CG-retransmission timer-r16 or CG-UCI, if the UL transmission is within the gNB FFP and ends before idle period of the gNB FFP, the UE shares the gNB-initiated COT for UL transmission. At this time, the COT sharing information field in CG-UCI needs to indicate that the gNB does not share ("no sharing"), which means that the UE does not perform UL transmission in the UE-initiated COT, and the gNB cannot share the UE-initiated COT at this time.

Referring to fig. 6, an embodiment of the present application provides a transmission apparatus, where the apparatus is applied to a terminal, and the apparatus 600 includes:

a determining module 601, configured to determine whether to perform uplink transmission in a first channel occupation time or in a second channel occupation time;
